Adding an On/Off switch to your Raspberry Pi

Conclusion

The options described in this article should provide a solution for most Raspberry Pi power management needs. One great thing about the Raspberry Pi is that it lets your imagination run wild. If you look at these solutions and think, "I wish I could add this functionality here," why not search the forums, blogs, and various other resources available in the Raspberry Pi community and have a play with your ideas. If nothing else, you will have fun in the process.

When the Raspberry Pi is connected to a car ignition or the USB port on a TV, you run the risk of data loss with a hard shutdown. The Pi UPS bridges short lapses in the power supply and shuts down your Rasp Pi safely when the power remains off.
